SAFE.

SPECIFICATION forming part of Letters Patent No. 594,378, dated November 30, 1897.

Application filed 1 1116 1, 1893. Serial No. 476,307- (No model.)

To all whom it may concern:

Be it known that I, THOMAS M. BRINTNALL, a citizen of the United States, and a resident of Medina, county of Medina, State of Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes, of which the following, with the accompanying drawings, is a specification.

My invention relates to What are known as circular-door safes; and its object is to provide said safes with an improved form of screw locking device, and also to provide such safes with an improved bolt-locking device which automatically locks the safe upon turn ing the safe-door through a partial revolution and to the combination of both my improved screw and automatically-operated bolt-lock to give a more secure fastening to the safedoor.

My invention consists in the construction and combination of parts illustrated in the drawings, described herein, and defined in the claims.

In the drawings, Figurel is a front elevation of a safe with my improvements. Fig. 2 is a central vertical section of Fig. 1. Fig. 3 is a view of the back of the door from the inside of the safe, a part of the cap which closes my automatic bolt-lock being broken away. Fig. 4 is an elevation of the back of my safe-door complete. Fig. 5 is an enlarged section which illustrates the vertical and horizontal adjustment of the ring which is carried by the crane-hinge and supports the safedoor. Fig. 6 is an enlarged detail of the pinion and segmental gear which are employed to turn the safe-door, and Fig. 7 is an enlarged broken section illustrating the arrangement of the puppet for holding the lock-bolts out of engagement with their sockets and the means for releasing said puppet to allow the bolts to be automatically thrown.

In the drawings the safe is represented as closed and locked.

The safe-body 1 is of the ordinary construction and has a circular front opening which is closed by a circular door, as hereinafter described.

WVithin the circular front opening of the safe-body 1 upon the inner side of the safe is fixed a ring 2, having the mutilated female screw 3. A swinging crane-hinge 4 is secured to the front of the safe by means of the bolts 5 and 5', which pass through the brackets 6 and 6, upon which bolts 5 and 5 the cranehinge 4 swings. A ring 7 is carried by the crane-hinge 4 and has vertical and horizontal adjustment with reference to the crane-hinge 4. The vertical adjustment of the ring 7 with reference to the crane-hinge 4 is secured by means of the screw-bolts 8 and ,8 and the nuts 9 and 9. To secure horizontal adjustment of the ring 7 with reference to the crane-hinge 4, I form sockets 4 in the ends of the cranehinges 4, as illustrated by Fig. 5, and insert .therein blocks 10, through which pass the vertical bolts 8 and 8. Said blocks 10 are given adjustment horizontally by means of the screws 11 and 11.

Upon the front face of the door 12 is fixed a ring 13. The ring 13 is grooved on its outer face and the ring 7 is grooved upon its inner face. The ring 13 fits within the ring 7, and the two grooves form a circular way 14, which have ball-bearings 15, as seen by the dot-ted lines iu'Fig. 1, for the purpose of more easily turning the safe-door. Upon the front of the ring 13 is fixed a circular plate 16, upon the upper side of which is fixed a segmental gear 17. This plate 16 closes the opening of the ring 13 to give the safe a neater appearance. The ring 13 may be as well a solid plate, but such construction would add to the weight and expense of the door without any corresponding advantages.

Upon the ring 7 is pivoted a pinion 18, which meshes with the segmental gear 17, and a gear 19 is pivoted upon the ring 7 to mesh with the pinion 18, and a crank 19 serves to turn the pinion 19. The pinion 19 turns upon a post 20, which projects through the cap 21, that closes over the segmental gear 17 and pinions 18 and 19 to give the safe a neater appearance and to protect said pinions and gear from dust collection. The crank 19 fits upon the outer end of the post 20. It will be seen that by turning the crank 19 the door 12 will be rotated independently of the ring 7. The employment of the two pinions 18 formed a puppet-hole 31. side of the plate 24 is fixed abracket or shell 1 and 19, instead of the employment of a single pinion to mesh with the segmental gear 17, that is attached indirectly to the door 12, causes the door to rotate in the same direction that the crank 19 is turned. This is done for convenience and to avoid confusion in rotating the safe-door.. It will be seen that the safe-door 12, with the ring 7, has a limited movement upon the pins or screwbolts 8 and 8, so that as the crane 4 is brought around to close the door the door will turn by means of said pivots 8 and 8 to letit swing straight into position in the circular front in the ring 23, is journaled upon the pin 26 an'dis provided with segmental grooves 27 Bolts 28, having studs 28 formed thereon, pass through lateral openings in the male mutilated screw-ring 23 and are adapted to engage sockets formed in the female screwring 2. The studs 28' travel in the segmental grooves 27.

Upon the plate 22 are fixed guides 29 for the bolts 28, which guides have vertical slots 29 to allow the bolts to travel out and in. Around the pin 26 is coiled a spring 30, having the two ends 30 and 30 secured to the segmental grooved plate 27. In the plate 27 is 32, through which passes a puppet 33, having puppet within the casing 32. A spring 34 is interposed between the top of the casing 32 and the ring 33. A throw 35 is pivoted to the plate 24 at 35.

To the female screw-ring 2 is-secured a trip 36, which trip 36 is adapted to let the outer end of the throw 35 pass under it and throw out the puppet 33 to the position illustrated by the drawings when the safe is locked.

In the plate 24 is formed a segmental slot 1 37, through which passes a pin 38, that is attached to the segmentally-grooved plate 27. By means of the pin 38 the plate 27 may be turned through an arc of a circle of the length of the slot 37. A dog 39 is pivoted to the plate 24 at 40 and has a shoulder 39, which is adapted to engage the pin 38. A link 41 is pivoted to the plate 24 above the free end of the dog 39 and has a lug 41 formed thereon, which lug is adapted to engage the free end of the dog 39.

1 stroke.

Upon the outer lated ring 2. the safe-door to lock it with the male and fe- 1 of the bolts. the right end of the slot 37, so that the pup- 42 represents the outline of a time-lock, which is secured to the plate 24.

Having fully described the construction of my improvements, I will now describe their operation. First, I will describe the manner in which the safe is opened, for the reason that it is illustrated as being closed and locked. At the time set the time lock 42 swings the link 41, as indicated by the dotted lines in Fig. 4, so that the outer end of the dog 39 is raised and the pin 38 is released from the shoulder 39. The spring 30 then throws around the plate 27, and the travel of the lugs 28 in the segmental grooves 27 Withdraws the bolts 28 from the sockets in the female ring 2 in which they were engaged. The pin 38 will strike against the left end of the slot 37 and prevent the plate 27 from turning beyond a fixed point. It will be seen that upon the release of the dog 39 by the timelock 42 my device automatically unlocks the bolts 28. By turning the crank 19 to the left the door is turned through a portion of a revolution, and the mutilated male screw becomes unlocked from the mutilated female screw, when the door may be swung open upon the crane-hinge 4. When it is desired to close the safe and lock it,the pin 38 is thrown to the right end of the slot 37, thereby swinging the plate 27 around, so that the puppet 33 will enter the hole 31 and hold the plate 27 rigid with the bolts 28 withdrawn to their extreme back The safe-door is then swung into place in the circular front opening of the safe and is turned to the right by means of the crank 19. As the crank is turned the male mutilated screw interlocks with the female mutilated screw and the outer end of the throw 35 engages the trip 36, withdraws the puppet 33 from the hole 31, thus releasing the plate 27 and allowing the spring 30 to operate to turn the plate 27 and throw the bolts 28 into the sockets formed in the female muti- It will be seen that by turning male screws it automatically locks by means When the pin 38 is swung to pet 33 enters the hole 31, the dog 39 drops by gravity, so that the shoulder 39 engages the pin 38 as the plate 27 turns back upon the release of the puppet 33 from the hole 31.

It will readily be seen that my improvement furnishes a form of screw-lock which is very effective and requires a shorter turn of l.
